351C Motorcraft D3AF DC Carb, needs new choke?
#1
Finally got my new (to me) 73 Mach1 out of the shop today with a handful of things fixed to it (was running too rich and getting too much gas and drowning the engine).

Anyways, the only real problem it is having right now, is you have to pump the gas a bit when starting it up, and sometimes let it run for a little while to warm up and idle correctly. My mechanic says that he thinks it needs a new choke, but he was unable to find one for it.

It's s 351c 2v with a Motorcraft D3AF DC on it. I'm a total newb to all of this, looking to learn, and this is my first bridge to cross.

Any ideas or recommendations? Bout the only thing I could find (based on a recommended shopping location from a member here in another thread) was this kit here: http://www.ohiomustang.com/store/order_p...itemid=823

But at $80, I'm starting to wonder if I should just save my money and use it towards upgrading to a 4 barrel?

On a side note, I guess that's not really the only problem. Every once in a while, the starter will stick on when turning the key for a good 10 seconds or so. I think I have read that it could be the solenoid or else in where the key is turning?

Any help greatly appreciated!

Yes, sounds like the good old days of carburetors!

It all depends on where you are headed with the car. If you are headed towards better performance then I think putting your money into a 4 barrel manifold and a new carburetor would be the way to go.

Don Witt at Ohio Mustang did have a very nice (used) Performer intake for sale. That and a good 4 barrel and you'll be on your way.

There is a possibility that you don't use your heat riser off your air cleaner snorkel. This would not allow the engine to get the heat it needs for your choke to work properly. Those 2 barrel carbs work great and have plenty of power for normal driving. Also the owners manual states that you must pump the pedal once before attempting to start the motor. The solenoid is your likely culprit on the starter problem.
